rest 应用demo 3 客户端的另一中方式

//rest接口访问地址特征
API_IP = http://localhost:8080/mano-vim
HttpClientRequest requestProvider = new HttpClientGetRequest(ConfigFileLoad.getConfContent("API_IP") + "/rest/provider_network_cn");

@Component
@Path("/")
public class ProvidernetRest {
@GET
@Path("provider_network_cn")
@Produces(ContentType.APPLICATION_JSON_UTF_8)
@Consumes(MediaType.TEXT_PLAIN)
public Object findProvidercnCount(@HeaderParam("X-Auth-Token") String token)
{
}

}

http://127.0.0.1:8080/mano-vim/rest（这个是要的）/provider_network_cn 

客户端：

@Override
public String findProvidercnCount(String token) throws Exception {

try {
String url = scapeRestRootUrl + "/token_api/ems_exist";
if ((null != token) && (!token.trim().equalsIgnoreCase(""))) {
url = url + "?X-Auth-Token=" + token;
}

String result = new String(HttpsUtil.getMethod(url));
return result;

} catch (Exception ex) {
logger.error("ex:" + ex);
throw ex;
}
};
